Espoo, Finland (SPX) Jan 04, 2017
Researchers at Aalto University, Finland are the first to develop a plasmonic nanolaser that operates at visible light frequencies and uses so-called dark lattice modes.
The laser works at length scales 1000 times smaller than the thickness of a human hair. The lifetimes of light captured in such small dimensions are so short that the light wave has time to wiggle up and down only a few tens or hundreds of times. The results open new prospects for on-chip coherent light sources, such as lasers, th ... read more

ALIAS Pushes the Envelope on Aircraft Automation
DARPA's Aircrew Labor In-Cockpit Automation System (ALIAS) program envisions flight operations with reduced onboard aircrew while improving mission performance and flight safety-all through a tailorable, drop-in, removable kit that would provide advanced automation to existing aircraft.
In two important steps toward that goal, DARPA has recently completed Phase 2 of this development effort ... more

China Plans to Launch 1st Mars Probe by 2020 - State Council Information Office
China is planning to conduct the first orbiting and roving exploration of Mars by 2020, the country's State Council Information Office (SCIO) said Tuesday in a report.
"China intends to execute its first Mars exploration operation, and grasp key technologies for orbiting, landing and roving exploration. It plans to launch the first Mars probe by 2020 to carry out orbiting and roving explor ... more

Thai junta chief hits back at web censorship critics
Thailand's junta chief on Tuesday defended amendments to a cyber security law that boosts censorship powers, slamming social media as a hotbed of immorality that needs policing.
Changes agreed to last week broaden the scope of the Computer Crime Act, which hands up to five years in prison for anyone found guilty of sharing "distorted" information online.
The toughened law has drawn a str ... more

China plans probes to far side, poles of MoonChina is planning missions to explore the far side of the Moon and to send robots to explore both lunar poles.
Plans to send astronauts to the Moon are also being discussed, according to Wu Yanhua, vice director of the China National Space Administration.
Wu told a press conference on Tuesday that work on the Chang'e-5 lunar mission, scheduled to make a soft landing on the Moon and r ... more

Oshkosh receives JLTV production modification
Oshkosh Defense has received a $176 million contract modification for the production of 409 Joint Light Tactical Vehicles for the U.S. Army.
The Joint Light Tactical Vehicle, or JLTV, is to replace some of the Humvees currently in service with U.S. infantry forces including the Army and the U.S. Marine Corps. Initial low-rate production for the armored vehicle began in 2016.
The ... more

Driverless platoons
As driverless cars merge into our transportation system in the coming years, some researchers believe autonomous vehicles may save fuel by trailing each other in large platoons. Like birds and fighter jets flying in formation, or bikers and race car drivers drafting in packs, vehicles experience less aerodynamic drag when they drive close together.
But assembling a vehicle platoon to deliv ... more

Tiny spy drones no match for Repellent-1 mobile anti-drone net
Russian engineers have completed development of a new mobile anti-drone warfare complex. Appropriately named the 'Repellent', the system is designed to suppress and destroy miniaturized enemy drones no larger than a few dozen centimeters and no heavier than a few kilograms.Russia's Izvestia newspaper reports that the system, first shown off at the Army-2016 expo in September, is now being consid ... more

Germanium's semiconducting and optical properties probed under pressure
Germanium may not be a household name like silicon, its group-mate on the periodic table, but it has great potential for use in next-generation electronics and energy technology.
Of particular interest are forms of germanium that can be synthesized in the lab under extreme pressure conditions. However, one of the most-promising forms of germanium for practical applications, called ST12, ha ... more

The Russian Space Systems holding, which belongs to the state-run Roscosmos space corporation, has created a new miniature electrostatic discharge measurement unit that can help extend the lifespan of satellite electronic equipment, the company said Tuesday in a statement.
"A miniature measurement unit for the electrostatic discharge parameters, created by the Russian Space Systems holding ... more

Football and prayer wheels: views of modern Tibet Faith has always been at the heart of Tibetan culture. As practitioners of the country's unique form of Buddhism face increasing obstacles to their worship, Beijing has sought to cultivate a different kind of true believer: the football fan.
China, which has fully controlled Tibet since the 1950s, has been accused of political and religious repression in the mainly Buddhist region.
It co ... more

Venerable Radio Telescope Sets Standard for Universal Constant
About 150 hours of observing time on the 1,000-ft radio telescope at the Arecibo Observatory in Puerto Rico over the course of the last several years have been devoted to determining whether the most fundamental constant in physics really is constant.
The target is the so-called fine structure constant, usually known as alpha, which describes the electromagnetic interaction between element ... more

MIT researchers reveal new technique for measuring gravity
Researchers have found a way to improve atom interferometers, the most common and precise tool for measuring gravity.
Atom interferometers measure difference in wave characteristics between atomic matter. They rely on an exotic state of matter called Bose-Einstein condensates. Researchers in MIT have found a way to improve the precision of atom interferometers by augmenting the condensa ... more

Stability challenge in perovskite solar cell technology
While solar cell technology is currently being used by many industrial and government entities, it remains prohibitively expensive to many individuals who would like to utilize it.. There is a need for cheaper, more efficient solar cells than the traditional silicon solar cells so that more people may have access to this technology. One of the current popular topics in photovoltaic technology re ... more
